1、多媒体技术应用基础知识点第一单元多媒体技术概述1.信息及其特征信息就是指数据、信号、消息中包含的意义。信息的特征:信息的表示、传播、存储必须依附于某种载体。信息就是可以加工处理的信息可以被存储、保留与传播。信息具有传递性与共享性信息具有时效性信息具有可伪性2.二进制与十进制、十六进制的相互转换(正整数位)(注:在考试中可使用计算器程序转换)二进制转换为十进制:按权相加法如(1101)21231220211 20 840113 十进制转换为二进制:除二取余法如 173D(10101101)B 方法如下:最后的余数从下往上取。二进制转换成十六进制:从二进制的低位开始,每四位二进制数转换成一位十六进
2、制数。反之,每一位十六进制数转换成四位二进制数。3.ASCII 码与汉字编码1计算机内的英文字符以二进制编码的形式来表示,其中使用最广的就是ASCII 码(即美国国家信息交换标准码)。标准的ASCII 码用一个字节中的7 个位来表示,可以表示128 中编码,其中数字、字母就是按顺序依次排列的。(ASCII 码表可参瞧书P6)。2汉字编码:汉字在计算机内也就是以代码形式表示的,这些代码称为汉字编码。汉字的编码有输入码(智能、五笔等)、交换码、处理码、字型码。其中交换码又称为区位码。常见汉字编码有:GB2312(使用 2个字节编码,包括一级汉字常用字与二级汉字非常用字)3用 UltraEdit 工
3、具软件观察内码时,ASCII 码只占 1 个字节,汉字编码占2个字节。4.多媒体数据压缩技术多媒体数据中存在多种数据冗余:空间冗余、视觉冗余、结构冗余、时间冗余多媒体技术应用基础知识点常用的多媒体数据编码与压缩的国际标准有:JPEG 标准、MPEG 标准、P*64 标准数据压缩的目的:节省存储空间。数据能被压缩的原因:首先就是数据本身存在冗余;其次在许多情况下媒体本身允许有少量失真。数据的压缩分为有损压缩(音频压缩MP3、静态图像压缩JPEG、动态图像压缩MPEG 等)无损压缩(用 rar 等压缩软件压缩的任何类型的文件)常见多媒体文件格式:无损 有损图像:bmpjpg 声音:wavmp3 视
4、频:avimpg 5、媒体及多媒体的概念(1)媒体的含义:媒体(medium)在计算机领域有两种含义:一就是指存储信息的实体,如磁带、磁盘、光盘等;二就是承载信息的载体,如数字、文字、声音、图形与图像等。多媒体技术中的媒体就是指后者。(2)多媒体及多媒体技术的概念多媒体就是指对多种媒体的综合,多媒体技术就是指以计算机为平台综合处理多种媒体信息,通常情况下,多媒体不仅指多媒体本身,也包括多媒体技术。6.多媒体技术特征多媒体技术有三个显著的特征:集成性、交互性、实时性。7、多媒体技术的应用(1)生活中的多媒体:MP3 音乐、影视动画、数字电视等。(2)多媒体技术的现状:音频技术、视频技术、数据压缩
5、技术、网络传输技术。(3)多媒体技术的发展前景:虚拟现实、多媒体数据库与基于内容检索、多媒体通信技术。8.多媒体计算机系统的组成(1)多媒体计算机的概念:多媒体计算机就是指具有多媒体信息处理功能的个人计算机。文档编码:CY3T9I1X1J6 HT1I2N5A6Y9 ZR5L3L5G10Z1文档编码:CY3T9I1X1J6 HT1I2N5A6Y9 ZR5L3L5G10Z1文档编码:CY3T9I1X1J6 HT1I2N5A6Y9 ZR5L3L5G10Z1文档编码:CY3T9I1X1J6 HT1I2N5A6Y9 ZR5L3L5G10Z1文档编码:CY3T9I1X1J6 HT1I2N5A6Y9 ZR5
